OIL-BURNER.

SPECIFICATION formingpartpf Letters Patent No. 737,676, dated September 1, 1903.

Application filed February 17, 1902. Serial No. 94,526. (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE W. SWARTZ, a citizen of the United States, residing at Huntsville, in the county of Madison and State of Alabama, have invented certain new and useful Improvements in Oil Burners, of which the following is a specification.

My invention relates to improvements in oil-burners; and the object of my invention is the provision of means for employing crude oil or petroleum where a crude oil or petroleum could be utilized for fuel, which. means can be easily applied and which will be inexpensive and practical for the desired purpose.

lVith this object in view my invention consists of a crude-oil burner embodying novel features of construction and combination of parts, substantially as disclosed herein.

Figure 1 represents a diagrammatic View of mechanism constructed in accordance with and embodying my invention, and Fig. 2 represents a det-ailview of the perforated coiled spraying-pipe.

In the accompanying drawings, I have illustrated my oil-burner in connection with a vertical or upright boiler; but it will be understood that I may use it with a horizontal boiler without departing from the spirit or sacrificing any of the advantages of my invention, and in the drawings A designates a tank or reservoir which contains the supply of crude oil or petroleum and which is placed in the most convenient and desirable place,

and from this tank leads the oil-supply pipe 13, provided with a valve or cock 0, and this pipe terminates at its upper portion with a coil D, which is provided with perforations E of varying or different sizes, and this coil is 0 arranged in the fire-box and in proper proximity to the boiler F. Leading also from the supply-tank is the forcing-pipe G, which is provided with a valve or cook II and is connected with the boiler, as at J, and the pipe is provided at its lower end with abend or nozzle K, which, as will presently appear, acts to force the oil from the tank through the supplypipe to the coil and to vaporize the oil.

A suitable air force-pump L is arranged adjacent to the tank, leading from which is a pipe M to the boiler, a branch pipe N to the supply-tank, and a branch pipe 0, which leads to and under the coil and has the perforations P therein, which are adjacent to said coil. The branch pipe N is provided with a valve or cock N, and the pipe 0 has a valve or cock 0. A suitable means for igniting the charge is arranged near the perforated pipe. Such means being of any construction and not forming in itself a part of my invention I have not deemed it necessary to show such igniter.

From the foregoing description, taken in connection with the accompanying drawings, the operation of my crude-oil burner will be readily understood, and stated briefly is as follows: When there is no steam in the boiler and it is desired to generatesteam, the air-pump is operated and forces the oil from the supplytank into the coil, and there the oil is sprayed and is mixed with the air from the pipe P and produces a vapor, which, when so mixed, is lighted by the igniter in the retort or fire-box. This makes a fuel of very high heating capacity and quickly generates steam in the boiler, after which the steam from the boiler passes down into the tank and forces the oil and vapor through the coil, where it mixes with the air from the air-pump. The valves in the different pipes can easily be operated to regulate the flow of oil, vapor, and air, as circumstances require.

The air-pump may be operated by handpower or fromthe boiler, as circumstances require, and the perforations E, being of Varyiug sizes, insure a better mixing of the oil and air.

1. In an oil-burner, the combination with a steam boiler, of a reservoir arranged in proximity thereto, an oilsupply pipe leading from said reservoir and having a valve,

a coil forming the terminal of the upper portion of said pipe and having perforations, said perforations being of varying size to insure a more perfect mixing, an air-pump, connection between the same and the reservoir, a branch pipe leading from said connection and extended beneath said coil and provided with perforations, a connection from said boiler to the air-pump and an independent forcingpipe connecting the reservoir with the boiler,

therewith, valves in said connection, a branch leading from said connection between said Valves, a perforated pipe communicating with said branch and disposed beneath said coil, and a valve in said branch, substantially as shown and described.

In testimony whereof I affiX my signature in presence of two Witnesses.

GEORGE WV. SVVARTZ.
